Analyze complex system requirements and translate them into efficient, maintainable designs
Develop and maintain automation scripts across development, test, and production environments
Promote code quality, reuse, traceability, and cross-team collaboration

Why Leidos
You'll work on systems where performance, precision, and reliability matter - every second. This is not experimental AI for proto@types. This is disciplined, responsible AI applied to mission-critical software that supports national infrastructure.
If you're excited by solving complex problems in regulated, real-world environments - and using AI as a force multiplier rather than a shortcut - we'd like to talk.
If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 - and moving faster than anyone else dares.
